Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, and in particular to an operating table for mouse perfusion procedures. Background Technology

[0002] In research fields such as neuroscience, histopathology, and pharmacology, cardiac perfusion fixation is one of the key steps in obtaining high-quality tissue samples. This technique involves sequentially perfusing physiological saline and fixative into the circulatory system of experimental animals (such as mice) to remove blood and achieve rapid and uniform tissue fixation, thus providing a good foundation for subsequent experiments such as immunohistochemistry, in situ hybridization, and electron microscopy.

[0003] Currently, most laboratories commonly use homemade, simple perfusion devices when performing cardiac perfusion in mice. These devices are usually temporarily assembled from common consumables such as foam boards, ordinary surgical instruments, scalp needles, syringes, and infusion tubing. Although they are inexpensive and use readily available materials, they have many technical drawbacks in actual operation, which seriously affect experimental efficiency and the consistency of results.

[0004] First, existing homemade devices lack dedicated animal fixation structures, making it difficult to stabilize the mouse's position and causing displacement during perfusion, which can lead to puncture failure or perfusion path deviation. Second, switching perfusion fluids (such as physiological saline and fixative) relies on manual operation, which is not only cumbersome but also makes it difficult to accurately control the timing and flow rate of switching, easily causing uneven tissue fixation or damage. Third, due to the lack of constant pressure or constant flow control mechanisms, the perfusion rate is unstable, affecting the perfusion effect, especially when processing large batches of samples with poor repeatability.

[0005] Furthermore, existing devices typically lack waste liquid collection systems, causing waste liquid generated during perfusion to drip directly onto the experimental platform, polluting the environment and posing biosafety risks. Simultaneously, the irritating odor released by volatile fixatives cannot be effectively removed, posing a potential threat to the health of laboratory personnel. More seriously, during manual liquid replacement or flow rate adjustment, air bubbles can easily be introduced into the circulatory system, causing vascular embolism and further reducing the quality of tissue fixation.

[0006] In summary, current mouse perfusion procedures based on self-made tools are insufficient to meet the requirements of modern biomedical research regarding standardization, safety, reproducibility, and ease of operation. Therefore, there is an urgent need to design a specialized operating table for mouse perfusion that is structurally sound, functionally integrated, and easy to operate, in order to solve the aforementioned technical problems and improve the overall quality and efficiency of perfusion experiments.
